Specification of Letters Patent.

Patented Apr. 28, 191. 1.

Application filed February 20, 1913. Serial No. 749,676.

To all 70730)]! it may (once/"n Be it known that I, JOHN citizen of theUnited States, residing at Chicago, in the county of Cook and State ofIllinois, have invented a certain new and useful Improvement in Tools,of which the following is a full, clear, concise, and exact description,reference being had to the accompanying drawings, forming a part of thisspecification.

My invention relates to tools and has for its object the provision of animproved kind of tool adapted more particularly for use in connectionwith repairs on single tube bicycle tires.

There are two prominent ways of repairing single tube bicycle tires. Oneis by the insertion of a metallic plug, having clamping members to holdthe same in place upon the tire, and the other system of repaircontemplates the use of rubber bands which in a stretched condition areinserted into the hole and are then permitted to expand and till theentire opening.

My invention contemplates the provision of a tool which may serve forboth classes of repairs, thus uniting in one instrument the function oftwo.

I will explain my invention more in detail by referring to theaccompanying drawing illustrating the same in which:

Figure 1 is a side elevation of my improved tool; Fig. 2 is a top planview there of, and Fig. 3 is a plan view showing details ofconstruction.

The improved tool of my invention consists of the spring clamp lterminating in two jaws 2 and The two jaws 2 and 3 are the extremitiesof the corresponding arms I and and may be clamped together through theagency of the bolt 6 and nut T. I preferably provide a circular recessat 8 to accommodate the ordinary metallic bicycle tube plug, which plugas well understood consists preferably of a metallic face plate with itsswiveled screw threaded extension carrying a nut between which nut andface plate the tire is clamped. My tool serves more particularly inholding this re J TOBIN, a

pair plug during the time that the tire is forced over the head. Thehead is held between the jaws 2 and 3, the circular recess 8accommodating the screw threaded plug. The tool acts in the nature of avise so that the tire can be readily forced over the plug head. Myimproved tool, however, is also capable of repairing a tire through theuse of rubber bands and to this end two washers l2 and 13 are pivotallymounted upon the bolt 6 The washers 12 and 13 have extending pins 14 and15 respectively, the pin let being provided with a notch 16 at itsextremity. These pins 1% and 15 are normally in place extendingbackwardly between the arms and 5 as shown so that the tool iscollapsible and may be carried in the pocket. Should the device berequired however to repair the tube the two washers 12 and 13 areclamped between the jaws, while rem ainmg upon the bolt (3 in such a waythat they extend at right angles as shown. Rubber bands 17 are thenstretched between them tightly, being inserted in the recesses l6, 16.The pin 1%l is then inserted into the hole 0'] the tube and the pressureupon the nut 7 released permitting the rubber bands 17 by virtue oftheir resiliency to swing the arm 15 into line with the arm 14-, therebyshortening these rubber bands and permitting them to expand within theaperture of the tube. Thereupon the pin 1% is withdrawn and the rubberbands entirely till the break in the tube. Jitter use the pins 14 and 15are then again swung baclnvardly between the arms 4 and 5. From this itwill be seen that the same tool serves two purposes and that it can becalled upon to repair holes in tires by either of the two prominent waysutilized.

It will of course be understood that my invention is capable of manymodifications without departing from its spirit, but

Having thus described one form of carrying out my invention, what Iclaim as new and desire to secure by Letters Patent is:

1. In a device of the character described, the combination with a pairor jaws, a bolt for clamping said jaws, and a pair of arms pivotaliymounted upon. said bolt said Jaws pivotafly mounted upon saidbolt andadaptaccommodating said arms between them ed to be clamped by said bolt.when not in use.
